Abstract
Chiral diferrocenyl diselenide was easily converted into chiral ferroc enylselenyl bromide by treatment of bromine in CH2Cl2/CCl4 at -78 degr ees C. This chiral electrophilic selenium reagent reacted with alkenes in the presence of methanol with high facial selectivity to afford se lenomethoxylated adducts in moderate yields.
